  The following embodiments of the present invention provide a method and system for mapping a plurality of virtual machines and a client device.

  In order to make those skilled in the art better understand the technical means in the embodiments of the present invention and to clarify the problems, features and effects of the embodiments of the present invention, the embodiments of the present invention will be described below with reference to the accompanying drawings. The technical means in will be further described in detail.

  Please refer to FIG. 1, which is a flowchart of an embodiment of a method for mapping a plurality of virtual machines according to the present invention.

  Step 101: The client device individually acquires display parameters of N connected display devices.

  In the present embodiment, the client device may specifically represent a thin client (TC) device. A plurality of peripheral interfaces configured to connect to the display device may be set on the client device, and the display device may specifically be a liquid crystal display. The client device may individually obtain the display parameters of the N display devices by calling the bottom layer driver, where N is a natural number of 2 or more. The display parameters may include usage status parameters of the display device. Further, the display parameters may further include the number of display devices, the resolution parameter of each display device, and the like.

  Step 102: When the client device is connected to M virtual machines, the client device individually receives virtual desktops pushed by the M virtual machines.

  In general, M virtual machines may be assigned to one user, and the user may obtain a list of M virtual machines by utilizing a client device. The client device may establish a desktop protocol channel between the client device and the M virtual machines and individually receive virtual desktops transmitted by the M virtual machines via the established desktop protocol channel. . M is a natural number of 2 or more and N or less.

Please refer to FIG. 1B, which is a schematic block diagram showing that a plurality of virtual machines according to this embodiment of the present invention are displayed on different screens. The client devices are individually connected to four display devices that are the display device 1, the display device 2, the display device 3, and the display device 4, and the client devices are the virtual machine 1, the virtual machine 2, the virtual machine 3, and the virtual machine 4 respectively. Are individually connected to the four virtual machines assigned to the user.

  Step 103: The client device individually selects display devices for the M virtual machines from the N display devices according to the display parameters of the N display devices.

  When a new virtual machine is connected, the client device checks the usage parameter in the display parameters of the N display devices according to the order in which the M virtual machines are connected, and the usage status in the N display devices. A display device whose parameter is “unused” is assigned to a newly connected virtual machine. For example, the client device may record the sequence numbers of a plurality of display devices in advance, and the use state parameter of each display device is initially “unused”. Referring to FIG. 1A, when the virtual machine 1 is connected to the client device, the client device may detect that the usage state parameter of all the display devices is “unused”. When the virtual machine 2 is assigned to the virtual machine 1 and then the virtual machine 2 is connected to the client device, the client device detects that the usage state parameter of the display device 1 is “used” and the unused display device 2 Is assigned following the virtual machine 2, and similarly, the display device 3 is assigned to the virtual machine 3 and the display device 4 is assigned to the virtual machine 4.

  Step 104: The client device outputs the virtual desktops of the M virtual machines to the display device individually selected for the M virtual machines in order to display the virtual desktops.

  In this embodiment, the client device displays the virtual desktop by calling the bottom layer driver, and outputs the virtual desktop of the M virtual machines to the display device individually selected for the M virtual machines. Also good. As can be seen with reference to FIG. 1B, the client device outputs the virtual desktop of the virtual machine 1 to the display device 1 for display, and outputs the virtual desktop of the virtual machine 2 to the display device 2 for display. The virtual desktop of the virtual machine 3 is output to the display device 3 for display, and the virtual desktop of the virtual machine 4 is output to the display device 4 for display.

  As can be seen from the above example, when a client device is connected to multiple display devices, the virtual desktops of the multiple connected virtual machines may be individually mapped to different display devices for display, This improves the use of the client device and satisfies the user's request when a plurality of virtual machines are used.

  Please refer to FIG. 2A, which is a flowchart of another embodiment of a method for mapping a plurality of virtual machines according to the present invention. The present embodiment shows a mapping process in which a plurality of virtual machines are displayed on different screens.

  Step 201: A client device individually obtains display parameters of N connected display devices by calling a bottom layer driver.

  See FIG. 2B, which is a schematic diagram of the internal logic of the client device implementing the embodiment in FIG. 2A. The client device has an operating system (Operating System, OS) kernel driver, a display processing module, and a protocol communication module. Here, an interface that can be called by the display processing module is set on the OS kernel driver. In practical applications, the functions of the display processing module and the protocol communication module in FIG. 2B may be integrated into one chip, the OS kernel driver may be stored in the memory of the client device, or the display processing module, The protocol communication module and OS kernel driver are all integrated into one chip.

  The OS kernel driver is a bottom layer driver set on the client device, and the OS kernel driver may be configured to detect display parameters of N connected display devices, the display parameters being It may have a usage parameter, and may further include the number of connected display devices, the resolution parameter of the display device, etc., where N is a natural number of 2 or more. The OS kernel driver may send display parameters of the display device to the display processing module via an interface between the OS kernel driver and the display processing module. As shown in FIG. 2B, the OS kernel driver may send display parameters of the display device to the display processing module via a P1 interface between the OS kernel driver and the display processing module.

  Step 202: When a client device is connected to M virtual machines, a desktop protocol channel is established between the client device and the M virtual machines.

  In general, M virtual machines may be assigned to one user, and the user may obtain a list of M virtual machines by utilizing a client device, where M is 2 or more It is a natural number of N or less. Referring to FIG. 2B, in this embodiment, each time a client device is connected to one virtual machine, a desktop protocol channel is established between the protocol communication module and the virtual machine, and the process of establishing the protocol channel is performed. Is the same as the process in which an existing client device is connected to one virtual machine, and details are not described herein again.

  Step 203: Receive individually virtual desktops transmitted by M virtual machines over established desktop protocol channels.

  Referring to FIG. 2B, after the desktop protocol channel is established between the protocol communication module and the virtual machine, the virtual machine pushes the virtual desktop data mapped to the protocol communication module via the desktop protocol channel. Alternatively, the protocol communication module sends the virtual desktop data to the display processing module for processing.

  Step 204: When a new virtual machine is connected, the client device checks the usage parameters in the display parameters of the N display devices according to the order in which the M virtual machines are connected.

  Referring to FIG. 2B, the display device display parameters reported by the OS kernel driver via the P1 interface are stored in a display processing module, where the display parameters include display device usage parameters. When assigning a display device to a virtual machine, the display processing module selects the display device from the display device whose usage parameter is “unused”, so it checks the usage parameter of the display device and newly connects the display device. Must be assigned to the virtual machine that was created.

  Step 205: Allocate display devices whose use state parameter is “unused” among the N display devices to the newly connected virtual machine.

  For example, the sequence numbers of a plurality of display devices are recorded in the display processing module. Initially, the usage status parameter of each display device reported by the OS kernel driver is “unused”. Referring to FIG. 1A, when the virtual machine 1 is connected to the client device, the display processing module acquires that the usage state parameter of all the display devices is “unused”, and the display device 1 When the virtual machine 2 is subsequently connected to the client device, the display processing module obtains that the usage status parameter of the display device 1 is “used” and an unused display. Device 2 is assigned following virtual machine 2, similarly display device 3 is assigned to virtual machine 3 and display device 4 is assigned to virtual machine 4.

  Step 206: The client device outputs the virtual desktop of the M virtual machines to the display device individually selected for the M virtual machines in order to display the virtual desktop by calling the bottom layer driver.

  Referring to FIG. 2B, the display processing module transmits coordinate information of each assigned display device to the OS kernel driver according to the display devices assigned to the M virtual machines, and transmits the virtual desktop data to the OS kernel driver. The virtual desktop data is transmitted to the OS kernel driver, and the virtual desktop of the virtual machine corresponding to each display device is output to the display device according to the coordinate information of the display device. Display the virtual desktop according to the display resolution parameter.

  As can be understood from the above embodiment, when a client device is connected to N display devices, the virtual desktops of M connected virtual machines may be individually mapped to different display devices for display. Often, this improves the use of client devices and satisfies user requirements when multiple virtual machines are used.

  Please refer to FIG. 3A which is a flowchart of another embodiment of a method for mapping a plurality of virtual machines according to the present invention. This embodiment shows a mapping process between an external device connected to a client device and a plurality of virtual machines after the virtual desktops of the plurality of virtual machines are mapped to a plurality of display screens.

  Step 301: When a client device is connected to an external device, the client device individually acquires a peripheral policy of M virtual machines and acquires a type of the external device.

  According to the embodiment shown in FIG. 1 or FIG. 2, after the virtual desktops of M virtual machines connected to the client device have been individually mapped to different display devices for display, the client device can, for example, be a headset. When connected to another external device such as an audio device such as an USB flash drive or an interface device such as a USB flash drive, mapping between the external device and the virtual machine needs to be performed. It is determined.

  In this embodiment, the interface device may include a parallel / serial interface device or a USB (Universal Serial Bus) interface device. Parallel / serial interface devices are classified into parallel interface devices and serial interface devices. The parallel interface represents an interface standard in which data is transmitted by a parallel transmission method, and the serial interface is an interface in which data is transmitted by a serial communication method. Represents a standard.

  In this embodiment, different virtual machine peripheral policies may be pre-stored in the client device, for example, for any virtual machine, all types of external devices may be mapped to the virtual machine, or It may be set that a certain type of external device may be mapped to the virtual machine. Therefore, when a client device is connected to an external device, the client device must match the peripheral policy of each virtual machine with the type of external device to match the external device type and the M connected virtual machine peripheral policies. To determine whether an external device may be mapped to these virtual machines.

  Step 302: Map external devices to L virtual machines whose peripheral policies match the type of external device.

  In this embodiment, a peripheral policy that matches the type of the external device is acquired according to a result of matching the peripheral policy of each virtual machine with the type of the external device, and the external device has the L number of policies corresponding to these peripheral policies. Mapped to a virtual machine, where L is a natural number greater than or equal to 1 and less than or equal to M.

  Step 303: Assign external device usage rights to at least one virtual machine in the L mapped virtual machines according to the type of external device.

  In this embodiment, when the type of the external device is an audio device, the client device may assign the right to use the external device to one virtual machine currently operated by the user by using the client device. For example, when a client device is connected to a headset and the headset is mapped to multiple virtual machines, the client device corresponds to a virtual machine that is currently controlled by mouse coordinates, ie, a display device that currently has mouse coordinates. A virtual machine may be acquired. A virtual machine is a virtual machine that is currently activated by a client, after which the client device releases the headset's audio output authority to the virtual machine, and other virtual machines can output audio signals. become unable.

  In the present embodiment, when the type of the external device is an interface device, the client device may assign the right to use the external device to one virtual machine that has requested the external device by using token negotiation. For example, when a client device is connected to a USB flash drive and the USB flash drive is mapped to multiple virtual machines, if multiple virtual machines request to write data to the USB flash drive, the multiple virtual machines are: The token request is transmitted to the client device, and the client device allocates a token to one virtual machine at a time according to the token request transmission order. After completing the writing of data to the USB flash drive, the virtual machine returns a token to the client device. Thereafter, the client device allocates a token to the next virtual machine until all virtual machines write data to the USB flash drive, and the token negotiation process ends.

  Please refer to FIG. 3B, which is a schematic diagram of the internal logic of the client device implementing the embodiment in FIG. 3A. The client device has an OS kernel driver, a peripheral processing module, and a protocol communication module. The M1 interface is set between the OS kernel driver and the peripheral processing module, and the peripheral processing module individually communicates with the protocol communication module by using the M2 interface and the M3 interface. In practical applications, the functions of the peripheral processing module and the protocol communication module in FIG. 3B may be integrated into one chip, the OS kernel driver may be stored in the memory of the client device, or the display processing module, The protocol communication module and OS kernel driver are all integrated into one chip.

  The protocol communication module may receive the peripheral policy pushed by the connected virtual machine and send the peripheral policy to the peripheral processing module. After detecting the event that the external device is connected to the client device, the OS The kernel driver reports the event and the type of external device to the peripheral processing module via the M1 interface, and the peripheral processing module maps the external device to the virtual machine that matches the peripheral policy according to the peripheral policy of each virtual machine, Here, according to the setting of the peripheral policy, it may be ensured that a certain virtual machine can exclusively occupy a certain type of external device.

  As can be seen from the above embodiments of the present invention, when a client device is connected to multiple display devices, the virtual desktops of the multiple connected virtual machines are individually mapped to different display devices for display. As a result, the use of the client device is improved and the user's request when a plurality of virtual machines are used is satisfied. Furthermore, when a client device is connected to an external device, the external device may also be mapped to multiple connected virtual machines, and the usage rights of the external device are assigned to the virtual machine according to policy control, thereby Improve the mapping flexibility of multiple virtual machines.
